• The speed of the BJT also drops in saturation. Example: Acceptable VCC Region EE105Spring2008 Lecture4,Slide5Prof.Wu,UC Berkeley • In order to keep BJT at least in soft saturation region, the collector voltage must not fall below the base voltage by more than 400mV. • A linear relationship can be derived for VCC and RC andWith Vin = 5V, VB = 0.746V and VC = 0.024V which means that the BJT is operating in the saturation region. But I don't understand why. Vcc = 5V and Vin = 5V. RB = RC = 1k ohm. So I expect that VB = VC and the base-collector junction is reverse biased which means that the BJT is in the forward-active region.…
